REVOLVING FAN.

SPECIFICATION forming part of Letters Patent No. 337,600, dated March 9. 1886.

Application filed November 1l, 1885. Serial No. 182,?(39. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY MENKE, Jr., of De Witt, in the county of Saline and-State of Nebraska, have invented a new and Improved Revolving Fan, of which the following` is a full, clear, and exact description.

My invention relates to revolving` fans adapted for use on dining or library tables, or at other places, for driving away flying insects, and for briskly circulating the air for cooling persons near the machine; and the invention has for its object to provide a simple, inexpensive, and effective device of this charac ter.

The invention consists in certain novel features of construction and combinations of parts of the revolving fan, all as hereinafter' fully set forth.

Reference is to be had to the accompanying drawings, forming partof this specification, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure l is a side view of the fan with the frame in vertical section, and the base and driving-gearing in section on the line xx, Fig. 2. Fig. 2 is aI plan view of the base with its cover removed to show the driving-gearing. Fig. 3 is an enlarged view of the driving-gearing removed from the base and as viewed in the direction of the arrow 1 in Fig. 2;4 and Fig. 4 is a side elevation of the case, showing, also, a preferred arrangement of spring'winding mechanism.

` oted to the cog-wheels D D, and so that while the wound springs are unwinding in the same direction the wheels D D will be rotated in like direction.

Each of the wheels D gears with a pinion, f, fast on a shaft, F, journaled in the frame B, and to which shaft also is xed a cog-wheel,

G. The two cog-wheels G G, which rotate in the same direction, mesh with a pinion, H,

which stands between them, and is fast on a shaft, I, to which is fixed a cog-wheel, J, which in turn meshes with a pinion, K, fast ou the driving-shaft L, to which the shaft M of the revolving fans N N is connected. The power of both the springs C C thus is utilized to rotate the fans. By using two springs they may each be made lighter than a single spring which will rotate the fans for any given time, and consequently the springs C C may be more easily wound up than could be a single heavy spring.

The driving-gearing is secured within a case, O, which forms the base or support to the fans, and to the top of the base O are attached a number of inclined uprights, o, having a cap plate or piece, o', in which the fanshaft M has a bearing. (See Fig. l.)

To the fan-shaft M is attached a head-piece, m, to which are pivoted the inner ends of the rods P P, which are entered through eyes or staples p p on the handles n n of the fans NN, and whereby the fans may be slid along the rods P P to set them nearer to or farther from the shaft M, to give them any desired sweep or range horizontally as they are revolving, and the rods P P are pivotally connected by rods R R with a runner or block, S, tted to slide on the fanshaft M, and provided with a set-screw, s, whereby the runner may be fixed to the shaft M at any desired height on the shaft for holding the fans N N higher or lower, as may be necessary or desirable, to cause the revolving fans to clear higher or lower objects on the dining or library table on which the machine stands, or to direct the air-currents from the fans to the best advantage for cooling persons near the fan.

The springs C may be wound up or putin tension by applying a key to the vertical spring-spindles A A; but I prefer to tix to each of the spindles a bevel-pinion, a, which meshes with a bevel-pinion, a', on a horizontal shaft, A', journaled in lugs on the case, and whereby the springs may be wound more conveniently by applying the key to the outer ends of the shafts A', as will be understood from Fig. 4 of the drawings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
